Is there a mobile app available to manage my Synology NAS remotely?

Yes, Synology offers a mobile app called "DS file" that allows users to manage their Synology NAS remotely. With the DS file app, you can access and transfer files to and from your NAS device, as well as browse through folders and open files directly on your mobile device. Additionally, the app supports offline file viewing, so you can access your files even without an internet connection. DS file also provides file sharing capabilities, allowing you to generate sharing links and send them to others. Furthermore, DSM (DiskStation Manager), Synology's operating system, offers other mobile apps like DS photo, DS video, and DS audio, enabling you to manage and stream media files stored in your NAS with ease.
